lMPROV EMENT IN LOOMS FOR WEAVING PILE FABRICS.

Speeificationforming part of Letters Patent No. 165,428, dated J u1y.13,1875 application filed May 28, 1:575. a

To all whom it may concern:

Be it known that I, STEPHEN SANFORD, of Amsterdam, county of Montgomery,State of New York, have invented a new and useful Improvement in WireMotions for Looms for and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings making part of this specification, in which Figurel is a back view of one of the end portions of a loom, and a portion ofa lay with shuttle-box, rigidly attached to and moving with it. ThisView shows how my wiremotion is combined with a rigid shuttle-box andlay. Fig. 2 is a front view of the same. Fig. 3 is a top view of thesame, the parts being in the position they occupy when the wire iswithdrawn from the cloth and the lay in the act of driving up the wirewhich has previously been inserted. The wire-supporting table is alsoshown by dotted lines in a position it is automatically adjusted to,when pressed back by a shuttle caught between the back of the wire-tableand the shuttle-box. Fig. 4 is a cross-section in the line 00 w of Fig.

2, looking toward the end of the loom; and i Fig. 5 is anothercross-section looking in an op posite direction in the line 3 y, Fig. 1.

The object of my invention is to render practicable the use of ashuttle-box, which is rigid with the lay, in connection with astationary wire-supportingtable, provided with a suitable wire motion,which withdraws the wires from the cloth and inserts them into the openshed. Another object is to relieve the shuttle, and prevent it beingbroken, in the event of the shuttle being caught between the lay and thewire-supportingtable; also, to atford facilities ,foradjusting thewire-table to a position which will permit the wires to be withdrawnbyhand, when necessity requires.

Another object of my invention is to eli'ect the withdrawal andinsertion of the wire on a practicallystationary table, with simplyalatch and pusher acting alternately upon the head of the wire, and asuitable device for carrying the point of the wire over to the point ofinsertion. Another object of my invention is to effect the properdirection of the wires into the open shed by a guide or guides betweenin nearly the same vertical the cloth and a wiresupporting table, whichhas its outer end elevated, and is provided with a suitable wire motion,and is so constructed that it permits a shuttle-box, rigid with the lay,to be used in connection with it. I Another object of my invention is toprevent the wires descending into the grooves of the table during theact of withdrawing and inserting the same, and thus avoid the necessityof lifting the point of the Wire to a position for the carrier toproperly take it across to the point of insertion.

To enable others skilled in the art to make and use my invention, I willproceed to describe it.

A is one of the sides of a loom; B, the shuttle-box, attachedrigidly toa lay, U. D is the wire box attached fast to the loom-frame. E is thewire-supporting table of the wire-motion, connected by its outer end toa standard, F, and at its inner end to the loom. F

is the reciprocating slide, which carries the withdrawing-latch G andpusher H. I is the first and J the second guide for the wires to theopen shed. K are the wires and L a lifter for elevating the wire-headsfor the latch to take them.

The supporting-table E is elevated on an incline from its inner to itsouter end high enough to permit the shuttle-box, which moves rigidlywith the lay, to pass under a portion of it, and thus allow the reed todrive up thewire which has been last inserted. Under this constructionthe relation of the groove of the table, in which the wire is inserted,to the shuttle-box is such that the shuttle-box stands plane with theinner end of said groove, when the reed is in contact with or driving upthe wire last inserted. In order to have the shuttle-box occupy thisposition a portion of its front flange is cut away, as at a, so as toadmit the shuttle-box to pass-under the laterally-extended portion 0 ofthe table, made through the rear flange or side of v the saidbox, sothat the guide I shall be passed without obstruction, as the shuttle boxis moved up with the lay. The said guide extends through the passagewhen the shuttlebox is forced up with the lay, and the reed is drivingup the wire last inserted.

and a passage, b, is

The wire-supporting table E is connected to its standard by a pivot, d,and to the loom I can be adjusted laterally, as illustrated by dottedlines in Fig. 3, so as to permit the wires to be withdrawn by handoutside of the portion 0 of the table. This is often necessary,

and my laterally-adjustable table for this purpose is a very importantimprovement.

Instead of having the table pivoted to its standard it may be madeyielding, or have a lateral movement in many other ways with- 4 outdeparting from the spirit of my invention.

The wire motion shown consists of a supporting-table with a singlegroove, M, and

- with an oblique switch-groove, N. The switch- I groove is formed inthe laterally-extended portion 0 of the table, and runs in a diagonaldirection from the groove, which is in line with the point where thewire is withdrawn 7 from the cloth to the point where the wire is .to beinserted into the open shed. The groove M has a spring-switch, Z, placeddiagonally across it. This switch is higher than the sides of the grooveN, so as to have a firm hold upon the side of thewire head and wire whensaid wire is being drawn back against it. The wire is, by means of theswitch, forced laterally in line with the inserting-groove at the momentthe head of the wire passes beyond the outer end of the intermediateoblique side of the groove N. While the wire is being forced laterallyby the switch lits head rests on the bottom of the table, while itspoint clears the upper edge of the sides which form the oblique groove.

In the withdrawing-groove a spring-guard,

I m, is arranged, so as to cross this groove and support the wire, andin the inserting-grooi e a spring-guard, n, is arranged in the samemanner and for a similar purpose. These guards prevent the points of thewires descending into the grooves, and thus render it unnecessary tolift the points of the wires to the proper position for being taken holdof by the device, (not shown,) which is used for carrying over thepoints of the wires to the proper place for insertion into the openshed. The guard it consists of a bevel-nose passed through the innerside wall of the groove N, this nose being on the end of a spring, a,arranged as shown.

The guide I is hinged to the top of the wire box D, and is formed withits interior surface flaring, like a portion of a flattened cone; and

. the guide J is simply a bent bar with a hookshaped ledge at one end.This latter guide is attaehedto the l0om-frame, so as to be adjustable.The relation of the guides to one another is clearly shown in thedrawings.

The reciprocating slide F, with its withdrawing-latch G and pusher H, issimilar to others heretofore used, and need not be more particularlydescribed.

The withdrawing-latch is moved up over and behind the head of a wire,and the latch takes hold of it, and carries the wire along the groove Muntil the head of the wire clears the partition between the grooves Mand N, when the spring-switch l moves the wire head in line with theinserting-groove N, and a carrier (not shown) takes the point of thewire across to the proper point of insertion. The pusher now forcesagainst the head of the wire, and drives the wire into the open shed.The wire in its passage to the open shed is controlled and directed bythe guides I and J until it reaches its proper place in the open shed.

It should be understood that the wire-supporting table E is,practically, a stationary table, while the parts are operating properly,and therefore the pivot d, on which this table is allowed to swinghorizontally, might be a rigid or fast connecting device, so far as theoperation of withdrawing and inserting the wires is concerned, for thetable is not intended to vibrate for the purpose of inserting the wireswith the pusher H after they are withdrawn by the latch. I thereforeprovide a spring stiff enough to prevent the wire-supporting tableyielding laterally and moving horizontally until danger of breaking theshuttle exists. The lateral yielding and horizontal movement of thetable are for difierent purposes than usual, and the direction ofmovement of the table is the reverse of other vibrating wire-supportingtroughs or tables. The wire heads may also be constructed so as not torequire lifting in the wire-box, and therefore the lifter shown forms nopart of my present claim, and my invention is not confined to its use.

. What I claim is-- 1. The stationary wire supporting table, elevated atits outer end, and provided with a wire motion. in combination with ashuttle box made rigid with the lay, substantially as and for thepurpose described.

2. The yielding wire-table, for relieving the shuttle-box when theshuttle is caught between the table and the box, substantially as andfor the purpose described.

3. The adjusting cam or lever z, in combina tion with the yieldingwire-supporting table, substantially as and for the purpose described.

4. The combination of a withdrawing-latch and an inserting-pusher, and astationary wire-supporting table, having a groove in line with the pointof withdrawal, and a groove leading to the point of insertion, and aspringswitch so arranged as to bear upon the wirehead, and place thewire in position for insertion in the shed, as and for the purpose de-'scribed.

5. The combination of the wire guide or tion with the stationary groovedwire-supportguides I and J with a stationary wire-suping table,substantially as and for the purpose portingdtable, which is elevated atits outer described. end, an is provided with a wire motion, andconstructed to permit a shuttlebox, which is STEPHEN SANFORD rigid withthe lay to be used, substantially as Witnesses: and for the purposedescribed.
